We’ve seen many devices to help the blind, but this is one of the coolest. BrainPort was first introduced in 2006. The idea was that it would allow users to regain some vision via a camera and electrical impulses sent to the tongue. Now we learn that the device may actually be available commercially very soon.
The BrainPort decodes signals from a camera on your head and transforms them into electrical impulses that hit your tongue, but gently, not joltingly. The impulses are then experienced as spatial awareness and even give one the ability to read text. Pretty amazing stuff.
